Gaming Rig (First Time DIYer)

My five year old computer's hard drive recently died. So, I am getting ready to buy a new one, and I figured I would try to build it myself. I have never built a computer, and I was hoping for some advice from people more knowledgeable. This build is just based off of my research for the past few days (even though I still don't feel like I know what I'm doing). I could be completely wrong. Any help is appreciated.
